A bad freezer compressor typically fails to start, makes unusual clicking or buzzing noises, overheats, or runs constantly without actually freezing. You can diagnose it by listening for its status, performing physical checks, and using a multimeter to test the internal windings.
A failing compressor is not something to be taken lightly. Left untreated, it can lead to more serious issues, like food spoilage or even a complete breakdown of your refrigerator.
Factors To Consider
Your compressor will usually last 8-10 years. If you start having issues with your compressor before this time frame, it might be worth looking into options for repair, but if it's hitting the average lifespan, it might be more worth it to replace entirely.
A compressor replacement is probably worth it if the refrigerator is less than 8 years old, is a high-end make or model, and is in otherwise good condition. Skip the repair if the cost is more than 50% of what the fridge is worth.
A low load on the refrigerator's evaporator and a heavier load in the refrigerating chamber can both lead to issues with the compressor. Running an empty fridge for a longer period of time and having a lot of ice in the freezer chamber are oftentimes to blame.
Based on national repair statistics and consumer feedback, Samsung and LG are generally the most problematic refrigerator brands, primarily due to complex features. Icemakers, water dispensers, and smart touchscreens are the leading causes of service calls across all manufacturers.
Resetting your compressor on your own
The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.
Often, a professional technician will advise you to purchase a new refrigerator instead of installing a new compressor on an old one. There are also very specific tools that you'll need to install the compressor that the average person doesn't own.
However, the typical lifespan of a fridge freezer is between ten and 15 years. If your appliance has developed a fault and is around this age, you should think about buying a new model rather than risk preserving an older fridge freezer that may keep breaking down.
The compressor may be damaged due to a few reasons like a broken compressor fan, start relay and faulty compressor. A broken fan will cause the compressor to overheat leading to poor performance. Overheating of the compressor will lead to overheating of the fridge.
Freezer compressor replacement costs between $250 and $650. The compressor keeps the temperature balanced in the freezer by moving coolant, or freezer gases, through the freezer unit. If the compressor malfunctions, it may be unable to achieve the desired temperatures or have uneven temperatures in different sections.
Reset Power
But compressor-related problems are too technical and often require specialized tools and training. You may need a professional compressor repair if: You've ruled out easy fixes, and the fridge still isn't working properly. You hear repeated clicking or an extremely loud, continuous humming.

Bottom-freezer refrigerators should be repaired within seven years and considered for replacement after that. Top-freezer refrigerators should be repaired within three years, considered for repair within three to six years, and replaced if older than seven years.
Amish communities keep food cold without modern electrical grids by relying on harvested ice, absorption refrigerators, and naturally cool environments like root cellars. These off-grid methods range from traditional ice harvesting to using highly efficient appliances powered by natural gas.
Compressor Troubleshooting Guide
Green = Run. The green run light indicates the compressor is running. If the indicator is dark it does not mean the unit is off. The compressor only runs when the compartment temperature is too high.
